Conor McGregor is still dealing with the repercussions from his outburst at Barclays Center in April.

A lawsuit has been filed by fellow UFC fighter Michael Chiesa against the Irishman stemming from his violent attack on a UFC team bus during UFC 223’s media day, TMZ Sports first reported.

According to the report, Chiesa is suing McGregor for assault, battery and intentional infliction of emotional distress.

Chiesa, who was on the bus at the time of the attack, suffered cuts to his body and face and was forced to withdraw from his fight with Anthony Pettis at UFC 223 days after the incident took place.

TMZ Sports noted that Chiesa said in the lawsuit he also suffered "severe emotional distress, mental trauma and/or bodily harm."

McGregor is slated to return to the octagon Oct. 6 at UFC 229 and will take on undefeated lightweight title-holder Khabib Nurmagomedov with hopes of regaining his crown. McGregor has not fought in the UFC since 2016 when he defeated Eddie Alvarez for the lightweight title.

UFC president Dana White announced after the altercation in Brooklyn that McGregor no longer was the lightweight champion.
